Polyquaternium 6 is used as a coagulant aid in water treatment.
PDADMAC can be used as an electrolytic solution in a variety of applications such as drug delivery, biomedical systems, and sensors, which include biosensors and chemical sensors.
Poly(diallyldimethylammonium chloride) solution (PDADMAC) is a cationic polyelectrolyte that is widely utilized as a flocculant. It is prepared by the radical polymerization of diallyldimethylammonium chloride (DADMAC) in presence of a catalyst in the form of an organic peroxide.
The monomer DADMAC is formed by reacting two equivalents of allyl chloride with dimethylamine.Poly(diallyldimethylammonium chloride) is then synthesized by radical polymerization of DADMAC with an organic peroxide used as a catalyst. Two polymeric structures are possible when polymerizing DADMAC: N-substituted piperidine structure or N-substituted pyrrolidine structure. The pyrrolidine structure is favored.
Polymerization of Poly(diallyldimethylammonium chloride)
Precipitate it from water with acetone, and dry the salt in a vacuum for 24hours. [Hardy & Shriner J Am Chem Soc 107 3822 1985.]
